What is the function of chordae tendinae?  What is a likely outcome from dysfunctiuon of chordae tendinae?

The chordae tendineae are thin, string-like structures located in the heart. They connect the papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle.

Their main function is to prevent the inversion or prolapse of these valves (which are responsible for preventing backflow of blood) when the heart contracts. In other words, the chordae tendineae help to keep the valves in place and ensure they function properly during the heart's contractions.

If the chordae tendineae were to become dysfunctional or damaged, it could lead to a condition known as valve prolapse. This is when the valve doesn't close properly, which can cause blood to leak back into the atrium. This can lead to various symptoms such as heart palpitations, shortness of breath, chest pain, and in severe cases, it can cause heart failure.

In some cases, a dysfunctional chordae tendineae may require surgical intervention to repair or replace the damaged valve.
